ROLL FOR BEATING-MACHIN ES.

Specification of Letters Patent. Patented Mar, 18, 1919.

Application filed May 7, 1918. Serial No 233,140.

To all whom it may concern:

Be it known that I, CLARENCE P. FoLsoM, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Rolls for Beating-Machines, of whichthe following is a specification.

This invention relates to certain improvements in rolls for beating engines. More particularly the improvements comprise means for securing the fly-bars in position on the roll so; that they are held securely while the roll is in action and may be conveniently removed and replaced as necessity may require. It is well known that rolls of this character are used for beating stock or pulp in the paper-making art and that in such usage the fiy-bars are called upon to withstand a very considerable amount of strain. Owing to this they must be securely 56 made fast thereon. The fly-bars, to be more held in position ina rigid manner and at the same time their replacement or removal must be free from dilficulty.

The drawings hereto annexed illustrate the improvements in connection with a roll and. willnow be referred to in general terms before giving. a more minute description thereof.

Figure 1 is a vertical sectional View of a roll of a beating engine, the same embodying my improvements. Fig. 2 is a somewhat enlarged fragmentary view of the periphery or ring portion of one of the supporting frames showing several fly-bars in position. Fig. 3 is a view partly in section on the line 33 of Fig. 2. Fig. 4 is a view on the line 4--4 of Fig. 2, the fly -bars appearing in section. Fig. 5 is a view of an end 0 one of the fly-bars. Fig. 6 is a detail view in perspective of one of the clampinghea'ds for the flybars. Fig. 7 is a detail view similar to Fig. 2 showing fly-bars held in position from both sides, and Fig. 8 is a detail viewin perspective of one of the clamping heads employed for holding each fly-bar from opposite sides thereof, as in Fig. 7.

In a more particular description of my improvements similar reference characters designate like parts in the drawings.

A beater roll is shown in Fig. 1 thesame comprising a series of spiders or annular frames 1. These are strung or assembled in proper relative positions on the shaft 2 and particularly described, are united to the peripheries of these frames and when so united the whole constitutes a beater roll. Each of the supporting frames 1 terminates in an annular margin or ring 3, the base of which extends laterally in an annular extension or flange 4. The ring or rather the flange portion 4 thereof is provided with bolt openings 5 which extend from enlarged openings on' the inner side of said flange 4. These bolt openings 5 lie at uniform distances throughout the circumference of the frame 1 and the periphery of each of said frames has uniformly spaced lateral openings 6 which taper outwardly on one side and receive the inner edges of the fly-bars 7. The two end frames 1 as shown in Fig. 1, re constructed so that the fiy-bar openings 6 have walls 8 inclosing them on the outer sides and forming shoulders against which the ends 9 of the fly-bars a-but when said fly-bars are mounted in the frames. The end bars 9 of the flybars are formed by cutting tlhe ends inwardly so that the outwardly lyin portions 9' of said fiy-bars will extend the ull width of the roll, so consisting of the assembled frames 1. As shown in Fig. 4 those portions of the fly-bars 7 that lie within the openings 6 are tapered on one side so as to have a wedge-like fitting in said openings and the outer portions of said fiy-bars are likewise tapered to a substantially knife-like form.

Each of said fiy-bars has oblong openings 10 at points where they pass through the peripheries of the frames 1. The ends of a series of clamping heads 11 extend into the openings 10 of each pair of adjacent fly-bars and hold said fly-bars to the frame through other means cooperating with said clamping heads. These other means consist of a series of bolts 12 which pass through the bolt openings 5 in the flange portions 4 of the frames, and the clamping heads 11 are provided each with a center openin 13'through which the bolts 12 also pass. uts 14 screw onto each of the bolts 12 and clamp the ends of the heads 11 firmly against the inner sides of the slots 10 in the fly-bars and thus firmly hold the fly-bars in position. Each of the clamping heads 11 is provided on the inner side at the ends with a shoulder 15. The ends of the said heads project into the fiy-bar openings 10 and the shoulders 15 abut with the adjacent portions of the fly-bars so that the said heads 11 cannot turn when clamped bars.

in position. Each of the nuts ii is provided with locking means consisting of a plate 16 through which the bolt 12 projects and against which the nut binds, said plate having a turned portion 17 which fits against one of the flat sides of the nut and thereby locks said nut from turning. Referring to Fig. 2 of the drawings it. would be there observed that the ily-bars 7 are held each from one side only by the clamping heads 11 as shown in Fig. 6. In Fig. 7 they re shown held at both sides by a form of clamping head 11 as shown in Fig. 8. This form of clamping head has the ends thereof reduced as at 18 in order that the ends of two of said heads may project into each opening 10 in a ll -bar from opposite sides of said fly-bar as shown in dotted lines in Fig. 7 and thus each fly-bar may be held firmly on both sides. It will be readily seen that the removal of a fly-bar is comparatively easy while at the same time the ily-bars are held in a most rigid and-satisfactory manner.

Having described my invention 1 claim:

1. A series of annular frames mounted upon a shaft, fiy-bars mounted in said frames, the whole constituting a beating roll, said fly-bar having openings therein, clamping members having openings therein and shoulders thereon, said clamping members engaging one or more fly-bars through the openings in said fly-bars, and bolts penetrating the openings in said clamping members and tightening the same against the fly- Q. In a roll for beating engines, a series of annular frames assembled upon a shaft and constituting a roll, said frames being or uni- Leer s72 form diameter and theperipheries thereof having lateral and radial openings, fly-bars mounted in said lateral openings, said flybars having openings therein, clamping members engaging each pair of fly-bars in said openings, bolts penetrating the radial openings in the peripheries of the frames and also penetrating the clamping members, and nuts cooperating with said bolts in tightening the clamping members.

3. A roll for beating engines comprising a series of rings mounted upon a common shaft, the periphery of each of said rings having a flange extending laterally on one side thereof, flybars mounted in said rings having openings therein, clamping members projecting into said openings and having shoulders which engage the fiy-bars adjacent to the openings therein into which said clamping members project, and means for rigidly securing said clamping members in the openings in the fly-bars.

&. A roll for beating engines comprising a series of rings mounted upon a common shaft, the periphery of each of said rings having a flange extending laterally on one side thereof, the filly-bars mounted" in said rings having openings therein, clamping members projecting into said openings and having shoulders which engage the fly-bars adjacent to the openings therein into which said clamping members project, and bolts penetrating the flanges of the rings and the clamping members and serving with the cooperating ot the nuts to hold said clamping members in position.

In testimony whereof I afi'ix my signature.
